Question

# An insulated collar is made to cover a pipe. Find the volume of the material used to make the collar. Let r = 3 inches, R = 5 inches and h = 21 inches.

Hint:

### Subtracting volume with *r* from the volume with *R*, we will get the volume of the material.

## The correct answer is: of the material used to make the collar The volume is 1056 cubic inches.

### Explanations:

Step 1 of 2:

Given, r =3 inches, R =5 inches and h= 21 inches

Volume with collar =

Volume without collar =

Step 2 of 2:

Volume of material used = volume with collar – volume without collar

cubic inches

Final Answer:

of the material used to make the collar The volume is 1056 cubic inches.
